Small star size orbs moving across the sky one of which flashed a white blue/green light and streaked away.

While watching the sky with a neighbor we witnessed a faint star size orb moving slowly from North to South across the sky. Our first thought was that it was a satellite. Within a few seconds another orb following roughly the same path was spotted and as we were watching this second one it flashed a very bright white light with a deep blue/green center, returned to the small size and then streaked away. We witnessed several more of these orbs including two flying in close proximity.
